Determining appropriate text height in model space?

[sammysparkle]

Hello all,

I sure need somebody to assist me on the techniques used in determining the appropriate text height in a drawing produced in Tiled model space.

Your comments will be appreciated!

OK- Here might be a good starting place...
Assuming you've drawn your geometry (2D or 3D) at 1:1 scale in model space, the question becomes: How can I scale my text so that when I Plot, text is properly sized? From this question, It may not be hard to see that you have to control this size relationship. It sounds harder than it is. Here's how:
After you've drawn your geometry (1:1) you can insert your properly sized title block around your geometry. You'll use the scale factor step in the insert command for this. If you have a fairly big part, or a plot of land, or some other drawing you've drawn that you know is obviously larger than an A-size sheet or B-Size, C-size, D-Size, E-size... , you'll have to scale the title-block "UP" to fit it over what you've drawn (1:1, remember?). The trick is, what "Factor" did you use to scale it up? If it was a standard one, the next step will be easier. Lets say you had to "double" the insert size of the title block to get it to look right, around your geometry (you used 2 as your insert scale factor). If you want 1/8" text, at plot, use 2x1/8, or 1/4. This is for regular text in the drawing. For dimensions, set standard text ht @ 1/8", and then in the "FIT" tab, set your sizing factor to 2.000. Don't give in to the temptation to reset the size of your dimensioning text to 1/4". Learn to manage scaling. One final note: This example assumed large geometry and a smaller title block. It can be the other way around. Just reverse scaling everything I've mentioned, and all should work ok.

Either way, if you've carefully sized the title block when you originally drew it (1:1 too, for instance 24x36 or 22x34 minus margins, etc., for a D-size drafting sheet), a "Plot to Fit" should give the desired results. Plotting to a detailed scale factor (2x T-block insert: 1/2x plot scale factor)is sometimes a requirement. Fortunately this approach handles those issues correctly as well!

Post back for more details- there's lots to this particular topic, none of it really complicated.

Good Luck!

I do all of my dimensioning, text, and borders in paper space, so the only thing I have to change is the dimscale for dimensions. If you prefer to write your text in model space, mulitply your text height by your dimscale.

p.s. text height x dimscale = m.s. text height
1/8" x 4 = 1" text height
(p.s. is paper space, m.s. is model space)

Here is my experience. You make tile block text height first that is 1:1. When you finished your model 1:1, then insert tile block to your model space, look at if that tile block fit with model. If it is ok, tile block text height is you want text height. If not, enlarge tile block, you text height is original text height X enlarge factor. It is very easy way to make text height.

Hopefully my answer is clear. If you have more questions you can send email to me at: lz244@hotmail.com

FECHO:
GREAT ANSWER! Virtually the same as mine, but shorter and more to the point! Like you, I draw my geom. 1:1 and insert the T-Block over it. For a small part (smaller than the sheet size) the T-Block might fit OK, or even be alittle large.

If you want to scale the T-Block down to fit closer and better around the part, just reverse your factor. Then take that factor and use it with the text Ht. ex: small part...insert t-block at say, 1/2 scale (.5) then when setting the text ht use .5 x .12 for your 1/8" text (=1/16 or .062 set text ht). Really pretty simple. Use the same factor in your dimensions scaling at the "Fit" tab in dimension styles dialog box.Then plot it to scale at 2:1.

For large parts, scale the title block up. ex: large part...insert title block, say 4x maybe. Thus 4 x .12 = 1/2" tall text, that will be 1/8" when plotted at the reverse factor of .25 (in the plot dialog box).

How about 1/8" text in a 1/4"=1' T-Block insertion? Same thing: 1/4" x 12"(1') = 48 (really 4x12). Insert the T-Block at 48x scale, and use 48 as your text ht. factor AND in your Fit Tab in Dimensions dialog. Then plot drawing to scale at the reverse, or 1:48 in the plot to scale part of the dialog box. Every enlarged factor works this way...1/8"=1',1/4"=1', 1"=10', etc.
Good Luck!

Hi all,
From my experience, and our office, the drawing sheet is inserted in paper space ( tilemode zero ) and is 1:1 - full size. All dimensioning is done in modelspace ( tilemode 1 ).
Create viewports in paperspace to the scale that will best fit your page - page size maybe A3, A1, A4 etc. In model space, set your dimscale to 10, do all the dimensioning, them in paper space create a viewport that is 1:10 by entering zoom entre, c enter, 1/10xp. The use of viewports is great, as you can have multiple, and can be many different scales. In different scaled viewports, you can turn off dimensions that dont suit the scale.

I have found that using AutoCAD 2002, there is a setting called dimassoc. Make sure your dimassoc is set to "2". this will allow to make associative realtime dimensions in paper space. Furthermore, they will be associative even if you move objects in model space.

Thus, you draw your geometery in model space 1:1, then in paper space your would have your title block, notations and all dimensions in paper space using only one dimstyle and ltscale. I change my viewport scale accordingly till the objects fit snuggly on the screen. using the tabs and page setups i preset all of the tabs to my desired plotting style via a template allowing me to plot all tabs as a batch plot. this is very handy and highly recommended...

Happy Cadding

Not sure if this is what you need but here is a good conversion table for standard text heights if you need your text in model space.
